Molson Coors Turns Out the Lights for Earth Hour

Global Brewing Company and Subsidiaries Participate in Global Initiative

DENVER, CO and MONTREAL--(Marketwire - March 25, 2008) - Molson Coors Brewing Company (NYSE: TAP) (TSX: TAP), one of the leading global brewers, today announced its
facilities around the world will turn off all non-essential lights on
Saturday, March 29, from 8 - 9 p.m. local time, in observance of Earth
Hour.

Earth Hour, run by the World Wildlife Fund (WWF) conservation organization,
is a global climate change initiative that calls on individuals and
business to turn off their lights for one hour.

"Earth Hour is an important reminder that individuals and companies alike
need to pay close attention to how our energy use impacts greenhouse gas
emissions, and at Molson Coors, our efforts don't stop when the lights go
back on," said Greg Wade, global chief supply chain officer for Molson
Coors. "We are always looking for ways to be more efficient and reduce our
use of energy."

The Molson Coors' Denver headquarters and Golden, Colorado-based Coors
Brewing Company will switch off all non-essential lighting outside the
offices and breweries. In Canada, the Molson breweries will turn off all
exterior lighting and signage, while UK-based Coors Brewers Ltd. will turn
off exterior lighting not needed for safety purposes.

Last year, more than two million people in Sydney, Australia turned off
their lights for one hour. This simple act reduced Sydney's energy
consumption by more than 10 percent. This year it is estimated more than
30 million people will take part in Earth Hour worldwide.

Molson Coors set a global target to reduce its energy use, indexed to
production, by 4 percent this year. As part of the U.S. Climate Leaders
Program, Coors Brewing Company plans to reduce greenhouse gas emissions by
an indexed 12 percent by 2010.

"Environmental stewardship is part of our overall corporate responsibility
commitment and that commitment is integral to how we do business," said
Bart Alexander, vice president, global alcohol policy and corporate
responsibility for Molson Coors. "It drives our participation in
initiatives like this and it is why we're also encouraging our employees
and their families to observe Earth Hour to help reduce energy consumption
at home."

Coors Brewing Company recently won an Xcel Energy Award for saving more
than 7.5 million kilowatt hours of electricity in its Golden facility last
year, using a multi-pronged approach to target nearly every area of the
company. Molson's Montreal brewery received the 2007 Leadership Award for
Metering and Tracking from the Canadian Industry Program for Energy
Conservation (CIPEC) for their efforts associated with late startup of
soakers/pasteurizers and steam pressure reduction. Coors Brewers Ltd. is
working with The Carbon Trust to pilot a new carbon footprinting standard.

as Coors Light, Molson Canadian, Molson Dry, Carling, Coors, and Keystone
